Detailed Description

Timer objects measure accumulated time in seconds. The timer object functions like a stopwatch. It can be started, stopped, and cleared. When the timer is running its value counts up in seconds. When stopped, the timer holds the current value. The implementation simply records the time when started and subtracts the current time whenever the value is requested.

Constructor & Destructor Documentation

Timer::Timer

(

)

Create a new timer object.

Create a new timer object and reset the time to zero. The timer is initially not running and must be started.

Member Function Documentation

double Timer::Get

(

)

Get the current time from the timer. If the clock is running it is derived from the current system clock the start time stored in the timer class. If the clock is not running, then return the time when it was last stopped.

Returns:

unsigned Current time value for this timer in seconds

Definition at line 85 of file Timer.cpp.

bool Timer::HasPeriodPassed

(

double

period

)

Check if the period specified has passed and if it has, advance the start time by that period. This is useful to decide if it's time to do periodic work without drifting later by the time it took to get around to checking.

Parameters:

period

The period to check for (in seconds).

Returns:

If the period has passed.

Definition at line 158 of file Timer.cpp.

void Timer::Reset

(

)

Reset the timer by setting the time to 0.

Make the timer startTime the current time so new requests will be relative to now

Definition at line 110 of file Timer.cpp.

void Timer::Start

(

)

Start the timer running. Just set the running flag to true indicating that all time requests should be relative to the system clock.

Definition at line 122 of file Timer.cpp.

void Timer::Stop

(

)

Stop the timer. This computes the time as of now and clears the running flag, causing all subsequent time requests to be read from the accumulated time rather than looking at the system clock.
